SPECIFICATION
IT IS THE ONLY CGMP MACHINE AVAILABLE IN INDIA
The
Riddhi Fluid Bed Dryer has adopted new concept of GMP Regulation with
improved performance (Drying time is much less than the conventional
model), minimum involvement of manual labour, simplified maintenance
and utilises modular construction techniques to provide flexible
installation options.
The
process unit is single piece made of SS-316 stainless steel. Thorough
mixing of Dry powders, Agglomeration and Drying all are carried
out in one unit of Riddhi Fluid Bed Dryer.
The
Outstanding Main Points of Riddhi Fluid Bed Dryer are as follows
:
PROCESS UNIT
-
The
Process unit is of single piece, made of stainless steel of SS-316
grade.
-
All
process contact parts are made of SS-316 grade.
-
The
finish employed externally will be all welds ground back and polished
into the surrounding materials.
-
All
of the external surfaces of the processor and all non contact/ sight
parts will prepared with a uniform fine texture matt finish.
-
All
of the product contact surface (SS-316) are mirror finished.
-
Particular
attention has been paid to reduce any source of material Entrapment
by mirror polishing flush all welds to create crevice free profiles
both internally and externally.
-
The
retarding and the expansion chamber containing the filter finger
bags are made of single piece construction from SS-316 quality sheet.
The length of the Expansion chamber is much more compared to retarding
chamber, thereby providing extra large heat exchange area which
exposes each and every particle or the charged batch in the Fluidised
air resulting in instant drying.
-
Side
entry inlet air duct at the rear.
-
Two
304 Stainless Steel support columns are provided for stability.
The Support columns designed to withstand a 30 ton vertical force.
-
Specially
designed base is provided for air vortex effect and to give added
strength.
-
A
central drain port is provided in the base to release wash water.
BOWL
/ PRODUCT CONTAINER
-
Product
Bowl is a conical shaped manufactured from SS-316 grade stainless
steel having stainless steel mesh support along with fine finished
air mesh.
-
The
product container Trolley is of Tubular construction made from
SS-304 pipe mounted on polypropylene castor wheel (2 Nos. Fixed
& 2 Nos. Swyvel for maneurverability) which imparts rigidity
to carry the product container with the charged load.
-
The
batch loading capacity is always higher in case of Riddhi Fluid Bed Dryer, because of better fluidisation by varying the frequent
shaking of the finger bags. Shaking period vary depending on the
nature of product.
RUBBER
GASKET
A
solid ‘U’ shaped food grade silicon rubber gasket is provided
in the groove of the flanged joint (between the product container
and the retarding chamber) to prevent any leakage of air with
fines during operation.
UNIFORM
LIFTING OF CONTAINER
Product
container is shifted by specially designed arrangement with the
help of one special Tee shaped Rubber with stainless steel inner
and outer guard operated pneumatically which ensures uniform Lifting
throughout the periphery of the container which ultimately gives
uniform upward pressure to the solid ‘U’ shaped Rubber Gasket,
thereby preventing any leakage during operation.
The
release of the product container at the end of operation is effected
smoothly by incorporating a specially designed vacuum generator
in the system.
SAFETY
CLAMP LOCKING
Pneumatically
operated safety Clamp locking system is provided for the product
container, with interlocking arrangement which will hold container
flanged joints continuously to prevent any leakage during operation.
This locking arrangement is an extra safety measure against any
explosion.
AUTO
SHAKING DEVICE
Pneumatic
cylinder is used for auto shaking device of the finger bags is
mounted on top thus rendering the shaking extremely efficient.
It also brings down the finger bags to such a level that these
can be inspected very easily from the bottom of the retarding
chamber. If the shaking is not efficient, the particle will be
retained in the finger bags and there will be no proper fluidisation
resulting in formation of lumps in the product container.
FILTER
BAG LOCKING TUBE
A
groove is provided in the retarding and expansion chamber impart
rigidity also to fit in an air tube with hanging ring (filter
bag locking tube) of the finger bags with interlocking device
(easily removable for cleaning or replacement). When expanded
the air tube sticks to the cylindrical surface of the filter holding
chamber to prevent by passing the fines emission and ensure arresting
of fines in the finger bags. Inspection sight glass is provided
within the side wall of the expansion chamber.
FLUIDISATION
CONTROLLER
An
Auto Damper controller, operated pneumatically, is provided on the
suction air ducting of the blower to control the pattern of fluidisation.
This helps
- To
avoid generation of more fines.
- To
have desired pattern of fluidisation for the materials of varying
bulk density by varying the quantum of suction air.
AIR
HANDLING UNIT
Blower
and Air filter with heating arrangements are housed separately in
the service zone to avoid sound pollution as well as to avoid interference
of the maintenance people in the production zone.
Blower
- Centrifugal
type blower fan with dynamically balanced impeller and backward
curved blades.
- All
mild steel construction with stove enamel paint finish.
- Direct
coupled non-flameproof electric drive motor. Anti-vibration mountings
and independent sub-support frame.
- A
sound attenuator will be fitted to keep noise emissions to
<
75 dB.
Air
Filter
Free
standing unit constructed from stainless steel frame work (SS-304)
with doubled skinned panels. All wall panels are cross based for
added strength. Quick release panels provided for inspection and
maintenance access.
The
air intake section has a full face external flange for attachment
of angle intact, or and extended inlet air duct.
Inlet
system comprising of 20 Micron washable filter, 20 Micron washable
filter is followed by 5 micron prefilter, then pass through, heating
coil section, containing a full air duct steam operated heater battery,
constructed with stainless steel tubes and headers and a steel casing
(SS-304). The moving process air passes through the steam heater
to achieve the desired temperature and then finally preceded by
HEPA FILTER of 0.3 micron (option) to match the inlet to the processing
unit.
A
304 Stainless steel transition section is fitted to convert the
inlet air duct from a square to a round configuration to match the
inlet to the processing unit.
PT
100 temperature sensing probe will be fitted into the Air Transition
Duct and will be connected upto the control panel.
EXPLOSION
VENT

per International practices, the equipment is provided with a
rapture Disc as measure of Explosion Vent, Tested at 2 Bar pressure,
Mounted on the side of the Dryer.
EARTHING
DEVICE
A
specially designed earthing device is provided with interlocking
system to Eliminate the electrostatic charges which develop due
to at-random movement of fines emission.
A
